To operate the device for retraction the screw 22 is loosened until it is free of the hole 24 after which it may be pulled inwardly in the direction of the arrow 42; this will carry the lower end or the slide 15 out of the window frame or channel 40. Likewise by unscrewing the wing nut 3311 the tooth, 30 will leave the detent groove 31 and the upper end of the slide 15 may be drawn out of the channel 40 by pulling the screw 33 inwardly in the direction of the arrow 43. Then by withdrawing the sash cord 18 from the slot 16 the sash may be readily withdrawn from the window frame.

The slide 15 may be provided either along one or both stiles of the sashes, one being sufficient for all practical purposes.

From the foregoing it will be seen that I have provided a simple yet efficient device which when attached to a window sash will'enable same to be withdrawn from the window frame for cleaning or other purposes.

Having described my invention what. I claim as new and desire to secure by Letters Patent is:

1. A window. sash having a longitudinal groove extending the entire longitudinal end edge of one of its stiles and horizontal grooves in the rails thereof, channel irons overlying the top and bottom of the said sash and horizontal grooves, a slide in the stile groove, an arm at each end of the slide extending into the channel irons and horizontal grooves, a spring member on each of the said arms, and screw operated detent means on the said arms and spring members for releasably locking the said slide when in extended position.

2. A window sash having a longitudinal groove extending the entire longitudinal end edge of one of its stiles and horizontal grooves in the rails thereof, channel irons overlying the top and bottom of the said sash and horizontal grooves, the top channel iron having a slot and detent grooves, a plate having a perforation therein in the lower rail groove, a slide in the stile groove, an arm at each end of the said slide extending into the channel irons, a spring member on the upper arm, a tooth on the said member passing through the arm, screw means passing through the spring member, arm and slot in the said upper channel iron for bringing the said tooth into and out of locking engagement with the detent grooves in the said upper channel iron, a spring member on the lower arm, and a screw passing through the said lower arm and spring member for engaging the hole in the lower groove plate for the purpose specified.

3. In combination with a longitudinally grooved sash and window frame, a longitudinal slide laterally slidable in the said sash groove normally extending into the window frame, arms at each end of the slide extending into the top and bottom sash rails guiding the said slide in its lateral movement, and spring detent means associated with the said arms for releasably locking the said slide when extended into the window frame.
